haveinvented certain new and useful Improvements in Hydrocarbon Motors,of

which the following is a specification.

"This-application is a division of application Serial No. 838,623, filedMay 11, 1914.

This invention relates to hydrocarbon motors,and particularly tomulti-cylinder mo- 'tors. One embodiment of the invention is shown andln-cludes a SIX cylinder motor 1n which there are two block castingsofthree cylinders each mounted. on a suitable base or crank case.

One of the objects of the invention is to produce a multi-cylinder motorof clean external appearance and one in which various parts of the motorare housed or inclosed.

Another object of the invention is to improve the water circulationsystem through the various aclrets of the motor, carbureter, etc.

Other objects of the invention will appear from the followingdescription taken in connection with the drawings which form a part ofthis specification, and in which:

Figure l is a side elevation and vertical sectional view of a motorembodying this in-- vention;

Fig. 52 is a plan view of the motor shown in Fig. 1;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1 withcertain of the cylinder heads and. valve sleeves omitted; and

Fig. 4.- is a view similar to Fig. 1. illustrating a slightly diliercntform of the invention.

In the embodiment oi the invention shown herein, the motor comprises sixcylinders cast in two blocks of three cylinders each. It will beunderstood that a lesser or greater number of cylinders may be employedand the cylinders may be otherwise cast.

Referring to the drawings, the base or crank case 10 is formed in twoparts, the upper or supporting part 11 and the lower part or bottomcover 12. The cylinder blocks or castings are shown at 13. there beingthree cylinders lei to each casting.

The up er end of each of the cylinders '14 is somewliat contracted, asshown particu- Specification of Letters Patent. Pat-rented J Divided andthis application lgebi'iiary larly in Fig. 1 forming a dome-shapedYeombustlon space 20 immediately above thefupiper limit of travel of thepiston ifij This contracted part of the cylinder isdouble walled and isof outward cylindrical form and constitutes a Water-jacketed head'forthe cylinder. In it are arranged suitable inlet ports 22 and exhaustports 23, preferably arranged in the same zone and both ofwhich areadapted to be controlled by a cylindrical or sleeve valve 24:. For thepurpose oi'getting a more perfect fit for the valve 24, it is sometimesdesirable to place a lining sleeve or collar 25 on the outside of thehead 21 said lining sleeve of course being provided with inlet andexhaust ports alining with the ports 22 and 23-formed in the cylinderhead. .1 Q The cylinder head 21 also provided/with a centre].depressionor cavity 26 in which a spark plug 27 is suitably arrangedin"c'ommunication with the interior of the cylinder or combustion space520. Thecentral ter1ninal 28 of the spark plug extendsflcbove the top ofthe cylinder head and the cavity 26 is closed by a suitable cap 290iinsulating material. i;

space continues up into the head 21. Water i is supplied for coolingpurposes by a pump 31 operated by suitable connections from the motorcrank shaft through pipes and 33, to the lower part of each of" thc'cylinder castings 13, as shown particularly; in Fig. 1. There is awater outlet from each oftlie heads 21 as shown at 3.4: in Fig. 15' andto all of these outlets is connected a pipe 35 which runs across the topof the'cylinders and coin nects with a suitable radiator, not shown inthe motor "tion therefor of a pipe 13, part 0 gether on the tops of thecylinders and form a compact arrangement thereon.

It will be understood that a suitable cylindrical space is left betweenthe exterior of each ofthe cylinder heads 21 and the interior walls ofthe head pieces 37, to form a valve chamber in whichthe valve 24operates, being rotatated by suitable mechanism to control the inlet andexhaust ports.

Means are provided for supplying cooling water to the head pieces 37,either from the pump 31 as shown in Fig. 1 in full lines, or by anentirel separate circulation system which woul include a slightmodification of the pipin arrangement shown in Fig. 1, such as s own inFig. 4. In the drawings, the jackets of the various head pieces 37 areconnected in series by short sections of pipe 39 (see Figs. 1 and 4. andin Fig. 1 apipe 40 leads. from the pipe 33 to the lower part of the headpiece 37 of cylinder number 1, and an outlet pipe l1 leads from theupper part ofthe head piece 37 of cylinder number 6 to thewater-jacketed part 42 of the carbureter 43. Also a pipe '44. leads fromthe lower part of the carbureter water jacket to the water jacket of oneof the cylinder castings 13. As above suggested, a modified form of thissystem is shown in Fig. 4 and nation of pipes 44 and 40 and thesubstitu- 45 extending from the lower part of the carbureter jacket 42to the head piece 37 of cylinder number 1. By the-latter arrangement,there is a constant circulation of water serially through the variousheadpieces, and'from head piece number 6 through the pipe 41 and carbureter water jacket 42 and from there through the pipe 45 back again tohead piece number 1. Thus the cooling action of the carbureter 4.3 actsas a radiator for the heated water from the head pieces, while on theother hand the hot water passing through the Water jacket of thecarbureter assists materially in vaporization of the gasolene. Thisarrangement of piping gives an entirely separate water circulationindependently through said head pieces comprises the 'elimieach cylinderhaving water jackets separate from the cylinder "water jackets, oi meansfor circulating water tl'ircugh ali of said head pieces in series.
